- This'invention relates to sawmill machinery and isprimarily concerned with mechanism for moving a log from a predetermined v position on a log deck onto a sawmill carriage, and for turning the log into any desired position on the sawmill carriage. v

In sawmills, as usually constructed, itlis necessary to provide an excavation below the log deck, and immediately in front of the logca'rriage, to permit the operation of the mechanism involved in loading and turning thelogs' f The main objecto'f the invention is to providea-log turner which can be placed directly 'o'n thefloor ofa ground mill and can be moved-very readily-as a whole from one location to-another. q f y Another objectof the invention is to provide a. log turner in'which the operating mechanism-occupies very little spac' e'vertically, and whichcan be very readily and cheaply manufactured; 1 I

Other objects of the invention will become apparent 'as the detailed descriptionthereof proceeds. I i In the drawings: r 1

Figure'Tis a section taken on the line 77 of Figure 2;

Figure 8 is a section taken on the line 8-8 V. of Figure 2; and Figure9 is a section taken on the line 9-9 of Figure 1. 3

- The mechanism as illustrated in the drawings comprises framework, designated gen erally by the reference character 1, and inon of the log turn- 5 eluding a pair of parallel rails 2 and 3, suit- 7 ably connected at their opposite'ends by standards 4 and 5. A cross rail 6 is secured to the bottom flanges of the rails 2 and 3.; and a steam cylinder 7 is fixed to the crossrail 6 with its axis parallel to the side rails ,2

Jamie and equi-distantly' spaced between them.

A slide designated generally by the reference'nume'ral, 8 (see Figure 8) is slidably mounted between the parallel rails 2 and 3. This slide comprises runners 8 and 9 connected to each other near one end by a cross rail 10 which is connected by pivot 11 to one end of apiston rod l2,'extending from the usual position (not shown) within the cylinder 7. i I 7 A shaft 13, provided at its opposite ends withrollers 14C and 15, is fixed to the runners 8 and'9 by means of the U-shaped clamps 16 and l? and pillow blocks 18 (see Figure 9). Angle iron plates 19 and 20 are suitably secured to the runners 8 and 9, respectively,

and have their upturned flanges 21 ,and'22 spaced apart to form a guideway for the log moving and turning'mechanlsm, designated generally by the reference character- 23.

The log turning, mechanism 23 comprises'a pair of arcuate plates 24 and 25 secured to each other at the lower ends by bolts or rivets 26 and 27, passing through spacers 28 and29 arranged between the arcuate plates 24 and 25.

A'log turning tooth member 30 has one end thereof pivoted between the plates 24 and 25 by means of the pivot 31. This tooth member 30 comprises a pair of plates 32 and 33 'securedto each other in spaced apart relationship by a plurality of rivets 84 passing through spacers 35 arranged between the plates 32 and 33. The log rolling teeth-36 of a form common in inventions of this character, are pivoted immediately above [the spacer plates 35 by means of the \rivets37, and normally hang 'by gravity against the spacer plates 35,.as' shown in Figure 6-of the drawings. y

"The toothed member 30 is swung about its pivot 31 by means of a link 38 (see Figure of the link 38 being pivoted to the end of a bifurcated lug 4O securely clamped to the shaft 13.

The plates 24 and 25 are pivoted on the shaft 13 and are rotated about said shaft by means of a piston rod 41 which is pivotally connected at one end to a pivot 42, suitably secured to the plates 24 and 25. The rod 41 slides through a packing gland 43 extending from a steam cylinder 44 which is piv oted at its center on suitable bearings secured to the runners 8 and 9 of the slide.

The log deck 1 comprises the usual runners'45 and 46, suitably supported on the framework and provided with stops 47 and 1 48. The runners terminate vertically over the standard 5 and are adapted to be positioned close to the track 49 upon whichthe carriage 50 is adapted to move.

The cylinders 7 and 44 are connected to the usual valve controls 51 and 52 to control the admission of steam thereto and the operation of the mechanism in general. These controls are old'and well known and are not illustrated in detail herein.

The operation of this apparatus will be obvious to persons skilled in this art from the foregoing disclosure.

While I have described my invention .as embodied in concrete form and as operating Y in a specific manner in accordance with the provisions ofthe patent statutes, it should be understood that I do not limit my invention thereto, since various modifications thereof will suggest themselves to those skilled in-the below said deck, a fluid motor fixed in said framework between said guideways, a slide reciprocable in said guideways, means connecting said motorand slide forreciprocating the slide, a log turner pivoted on said 7 slide, and a fluid motor carried by said'slide for operating said log turner.
